WiFi Issues On TCL Roku TV: How To Fix [2023]

The joint venture between Roku and TCL has brought forward the TCL Roku TV, and it is a beast. But it does struggle with WiFi at times, and that's disappointing.

Fret not, for I have conjured up some of the best troubleshooting fixes that you can try out with ease once the WiFi starts to act up on your TCL Roku TV.

If you have WiFi issues on TCL Roku TV, check the network status and reboot the Router/Modem. Disable firewalls, VPNs, and other network masks on your network. Power cycle the TCL Roku TV and update the TV firmware. Factory resetting the TV could also help resolve the issue.

Let's now take a brief look at the many possible instances of WiFi failing on a TCL Roku TV:

Scenario	Causes and Fixes
TCL Roku TV showing error codes	Bad network connection; check and restart the Router. Change the password to a simpler one
TCL Roku TV not connecting to WiFi but other devices can	Device IP may be blocked; Disable IP masks, VPNs, and other network filters
WiFi frequently dropping on TCL Roku TV	Unstable network; switch network bands
Other scenarios	Factory Reset TCL Roku TV; contact customer support

Basic Network Connectivity Troubleshooting

More often than not, the simpler things tend to cause issues that leave us in the dark. For instance, do not try to connect wirelessly while you have a wired connection plugged in.

Check your connection status. This will give you a well-found understanding of your WiFi and internet issues.

To check the connection status and speed, follow these steps.

1. On the Home screen, click and open Settings.

2. Scroll and select Network.

3. Click on Check Connection to test the connection speed and status.

4. From the result, you can assess the status and connection details.

A red cross next to the wireless connection line indicates a connection failure with the WiFi. If the MAC address line is zeroed out, your device must be blocked by the router (more on this later).

Here are some tips to solve the issue:

Check the WiFi Connectivity

Let's try the old trial-and-error method. If you cannot establish a connection with your network, either the problem is with your TV or the Router.

To weed out the culprit, connect another device to the WiFi, like your phone or PC.

If you can connect the devices and access the network, you may have a substantial issue at hand.

In such cases, either it might be a fried WiFi chip on the TV or some router intervention that impedes connection with the TV. If you cannot connect the device, check the router for issues.

Connecting the TV to another network, like a wireless hotspot from your phone, should do the trick. If you can connect to the network, the issue is definitely with the router or the home network.

Refresh the Network/Router

Most issues with the network can be resolved by a quick refresh unless you have modified any settings. The best way to refresh the connection is to power cycle the router.

Unplug the device and plug it back in after a few seconds. This will wipe out any temporal bugs and errors on the router.

Connect back the TCL Roku TV to the network and check for the issue now.

Change the Bandwidth

Another likely fix to try on the TV is to change the network. TCL Roku TVs have multi-band support, meaning you can connect to a wider bandwidth.

And so, better change the connection to a 5 GHz connection, a wider bandwidth, to forgo any latency and network traffic issues.

To change the network on your Roku TV,

1. On the Home screen, click and open the Settings tab.

2. Click on Network and select Set up a new Connection.

3. Click on Wireless and select the 5 GHz band network.

4. Enter the password to establish the connection.

If you are already connected to a 5 GHz band and have no access to the internet, connect the TV to the traditional 2.4 GHz band.

Even though it may have latency problems under heavy load, the 2.4 GHz band provides a much better connectivity range compared to the 5 GHz band.

Forget the Network and Reconnect

Now, let's disconnect the current WiFi network and reconnect to the same network after a quick restart. It has proven helpful even if it sounds absurd.

To remove the connection, follow these steps.

1. On the Settings tab, click and open Network.

2. Select your WiFi connection.

3. Click on Forget Network and select OK.

After a quick restart, reconnect to the network and check for problems. This may also come in handy when the TV shows error codes like Error Code 003 or Error Code 009.

Check for Interference

Interference between the Router and the TV can cause the connection to be glitchy. Make sure you have no other wirelessly transmitting devices in the vicinity of the TV.

Most modern gadgets (like a gaming console or a home automation device) require network access to fully utilize all their features, which in turn may induce interference to nearby devices.

Make sure to turn OFF the wireless transmission or relocate any such devices from the premises.

Try relocating the router to a nearer location if the signal strengths are unsteady.

Restart the TCL Roku TV

If your TV has been running for a long time, efficiency and ease of use may get affected by the bugs and errors that accumulate over time.

A simple restart or a power cycle test can clear off these bugs and errors.

To power cycle the TV, simply unplug the TV from the socket, and plug it back in after a few seconds.

You can also try and restart the TV using the TV's interface.

To restart the TCL Roku TV,

1. In the Settings tab, click and open System.

2. Click on Power, followed by the System restart option.

3. Then click on restart.

Wait for the TV to reboot and then, try connecting to a network.

Check for Updates

Running the TV on outdated firmware pretty much opens the doors for all the bugs and errors out there to roost on your system.

These bugs and errors will cause problems similar to the ones at hand, and they may not be limited to just connectivity problems, with one prominent issue being UI freezing.

Make sure you are running on the latest firmware to avoid such inconveniences.

To check and update to the latest firmware, follow these steps.

1. In the Settings tab, click and open System.

2. Select System Update.

3. Click on Check Now to manually scan for any updates.

Apply the updates, if any, and restart the device. Connect to a network after restarting the device and check for the issue.

Check the Time Setting on TCL Roku TV

Proven to be an area of possible bug infestation, this setting should not be overlooked as an improbable culprit.

Setting the time on your device has become a necessity, especially if you want to avoid possible network issues.

By default, it will be set to adjust automatically through the available network. You will have to disable this option and manually set the date and time.

To do so, follow these steps.

1. In the Settings tab, click and open System.

2. Click on Time and then select the Time zone option.

3. Disable the Set automatically tile and select the Set manually option.

4. Proceed to enter the right time zone.

5. You can also choose the clock format if you want to and then exit the menu.

After a quick restart, try connecting to the WiFi.

Disable any Filters and VPNs on the Network

Pi-holes and other filters may help you play it safe in the long run, but they may also cause connectivity issues on certain devices.

Likewise, VPN services also hinder connectivity by providing high latencies and unstable signal strengths.

It is highly recommended to disable such contraptions on the network as a probable solution for this issue.

Check the Router Settings

Changes made to the router can affect the connectivity on your Roku TV. Make sure to revert these changes to default before establishing a connection.

You can access these settings by connecting the router to a PC and opening the router portal through a browser.

Once you have connected the router, enter the IP address of your Router into the search bar of the browser.

You will have to log in to your account by entering the login ID and password. Default credentials- ID: Admin, Password: password.

Then try these steps and check for connection.

Changing the Password and Downgrading Security

A complex password for the WiFi can make the connection cumbersome. Make sure to change a complex password to a simpler one. Avoid numerals and special characters in the password.

If changing the password was unsuccessful, try removing them completely. This is a great way to check if the problem is with your password.

If you were successful in establishing a connection, try a simpler password for the WiFi.

You can change all of these settings by accessing the WiFi menu once you have logged into the account.

Switch the WiFi Channel

Changing the WiFi channel can make your connection more stable and efficient. If the current channel has a high amount of traffic, you won't be able to get a proper connection on your TV.

To change the channel, you will have to find the Wireless connectivity settings under the Advanced setting on your router portal.

Once you select this menu, you will be able to find the channel in use. Select 1, 6, or 11 for the 2.4 GHz band and the lowest available channel for the 5 GHz band.

Check the Mac Address Filtering List

While checking the connection status on your TV, if the MAC address line is zeroed out, your device might be blocked by the router.

You can confirm this issue by checking the MAC address filtering list on your router portal.

Try and find the portal under the WLAN or Wireless connectivity option. Check if the MAC address of your TV is on the list. If so, remove it from the list

After a quick restart, try connecting to the network.

Check the DNS Setting

If you have changed the DNS address on your router to a different one, you might face problems with the connection.

Error codes like 014, 014.30, and 014.40 are all associated with network errors.

To fix this, revert the DNS to the ISP-recommended one and restart the device. Check the connection now.

Factory Reset the TCL Roku TV

The last straw, so to say, is to reset your Roku TV. A hard reset will remove all the temporal bugs and dormant files that eat up the memory and render the system slow.

It will also reset all your personal preferences and settings, leaving the system in its factory state.

To factory reset the TCL Roku TV,

1. In the Settings tab, click and open System.

2. Click on Advanced System Settings.

3. Select Factory Reset and enter the special code.

4. Click on OK to confirm the reset.

Wait for the process to complete and then reconfigure your Roku TV.
